Özet

Behcet's disease is a chronic multisystemic disease with remissions and relapses. Several studies have shown that immune mechanisms play an important role in the development of the disease. In order to assess the association of disease activity with IL-17A/F, IL-23, IL-12/23 (p40) and IL-35 expression, we aimed to investigate production of these cytokines in peripheral blood mononuclear cells (PBMCs) from Behcet's patients and normal controls. Furthermore, we included Systemic Lupus Erythematosus (SLE) as disease control to evaluate the specificity of our data for immunopathogenesis of BD. Totally 15 active, 15 inactive Behcet's patients, 12 active and 12 inactive SLE patients and 12 healthy volunteers were enrolled in the study. Peripheral blood mononuclear cells were separated, lymphocyte cultures were performed and IL-17A/F, IL-12/23 p(40), IL-23, IL-35 cytokine levels were measured by ELISA in culture supernatants in the presence or absence of phytohemagglutinin (PHA) on time-dependent manner. IL-17 A/F levels increased parallel to IL-23 levels in Behcet's and SLE patients. Compared to healthy controls, IL-17 A/F levels were higher in active Behcet's and SLE patients; on the contrary, levels of IL-35 were lower. IL-17A/F, IL-12/23 (p40) and IL-23 levels were detectable most frequently in active Behcet's patients followed by active SLE patients. Our results indicate that IL-17 A/F, IL-23 and IL-12/23 (p40) may play role in the immunopathogenesis of BD so as Th17 and Th1 cell responses. Since IL-35 levels were lower in active Behcet's patients compared to inactive patients and healthy controls, there may be a plasticity between Th17 and Treg cells according to the state of disease activity.
